Open Transport Data, 2018

The EU directives PSI and Inspire state that public data must be shared and the ITS directive requires open transport data. The purpose is to promote innovation in new services that society needs. But development is slow. There are many barriers to opening data. At the same time, finding and using open data is challenging. Knowledge is needed about how data should be opened to make it easy to find, understand and use the data. The project has mapped barriers and success factors related to the use of open data, and tested various tools and solutions for publishing and using data. Based on this, advice has been drawn up on how open data should be published and used. The councils include: use of metadata, documentation, APIs and licenses. The tips are summarized here: http://opendatalab.no/ Experiments have also been carried out with automatic annotation (metadata registration) and semantic search for open data. The results show that this can work well if the data sets have good documentation in natural language. Data are freely available for downloading after 01.06.2020.

欧盟的PSI指令与Inspire指令规定公共数据必须共享，而ITS指令则要求开放交通数据。其目的是推动社会所需新服务的创新。但发展进程较为缓慢，数据开放面临诸多障碍。同时，查找与使用开放数据也具有一定挑战性。我们需要了解应如何开放数据，才能使其易于查找、理解和使用。该项目已梳理了开放数据使用相关的障碍与成功因素，并测试了多种数据发布与使用的工具及解决方案。基于此，项目制定了关于开放数据应如何发布与使用的建议，包括：元数据的使用、文档编制、API及许可证。相关建议总结于此处：http://opendatalab.no/。此外，项目还开展了开放数据自动标注（automatic annotation）与语义搜索（semantic search）的实验。结果表明，若数据集具备良好的自然语言文档说明，上述方法可有效发挥作用。数据自2020年6月1日起可免费下载。
